CDM-570A/570AL Satellite Modem with Optional Packet Processor
Revision 5
Updating Firmware 4–2 MN-CDM570A
4.1.1 About Firmware Files, Naming, Versions, and Archive Formats
Comtech EF Data’s Web site catalogues its firmware update files by product type (e.g., modem,
converter, etc.) and specific model/optional configuration. For example, the Base Modem bulk
firmware download hyperlink appears as F0020683*_V### (where ‘###’ indicates the firmware
version number, and ‘*’ is the revision letter of that version).
In addition to this Base Modem bulk firmware archive file, downloads are available for the
CDM-570A/570AL’s optional Packet Processor. Firmware updates are available from Comtech
EF Data as follows:
Web Hyperlink EXE/ZIP Filename
Contains Image File ( where ‘ * ‘ denotes revision letter and
‘#.#.#’ or ‘#_#_#’ denotes FW Version number)
F0020683*_V### FW-0020683*
FW-0020683*_#.#.#.bin
Base modem firmware
F0020781*_V### FW-0020781*
FW-0020781*_CDM570A_PaP_#_#_#.bin
Packet Processor Module option without 3XDES Encryption.
(3XDES Encryption is a future offering.)
The firmware download files are available from Comtech EF Data in two archive file formats:
*.exe (self extracting) and *.zip (compressed). Some firewalls will not allow the downloading of
*.exe files; in this case, download the *.zip file instead. If applicable, one version prior to the
current release is also available for download.
For additional help with "zipped" file types, refer to the help files provided with
the "PKZIP for Windows", "WinZip", or "ZipCentral" file archiving programs.
“PKZIP for Command-line” is not supported due to file naming conventions.
To verify the correct firmware number, see Step 1(d) in Sect. 4.2.1 Getting Started: Prepare
for the Firmware Download.
